Conditions
Brief summary
The goal of this observational study is to assess the clinical outcomes of binocular implantation of Asqelio EDOF Toric IOLs in healthy cataract patients. The main questions it aims to answer are: * What is the visual performance at different distances 3 months after implantation of Asqelio EDOF Toric in both eyes? * What is the amount of residual refractive error following the implantation? * What is the contrast sensitivity of patients 3 months after implantation of Asqelio EDOF Toric in both eyes? * What is the optical quality of the eye implanted with Asqelio EDOF Toric IOL? * What is the incidence and severity of visual symptoms after implantation of Asqelio EDOF Toric? * What is the level of patient satisfaction after implantation of Asqelio EDOF Toric? For this purpose, participants will be submitted to a comprehensive visual and refractive assessment, following common clinical practice, 3 months after binocular implantation of Asqelio EDOF Toric IOLs, and asked to complete visual symptoms and patient satisfaction questionnaires.

| Uncorrected Monocular Visual acuity for intermediate distance | 3 months after implantation | Visual acuity without additional correction determined at a distance of 67 cm in LogMAR units |
| Uncorrected Monocular Visual acuity for near distance | 3 months after implantation | Visual acuity without additional correction determined at a distance of 40 cm in LogMAR units |
| Corrected Monocular Visual acuity for distance | 3 months after implantation | Visual acuity with best correction determined at a distance of 4 m in LogMAR units |

| Corrected Monocular Visual acuity for near distance | 3 months after implantation | Visual acuity with best correction determined at a distance of 40 cm in LogMAR units |
| Refractive error | 3 months after implantation | Residual refractive error after implantation obtained by subjective refraction methods |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Patient-reported visual symptoms | 3 months after implantation | Incidence and severity of visual symptoms, determined by means of a visual symptoms questionnaire. Incidence will be scored in a scale from 1 (never) to 4 (always), severity from 1 (none) to 4 (severe), and bothersome rom 1(none) to 4 (a lot) |
| Contrast sensitivity function under photopic conditions | 3 months after implantation | Contrast sensitivity measured under photopic conditions for spatial frequencies of 3, 6, 12 and 18 cycles per degree using the Clinical Trial Suite in logCS units |
| Incidence of Adverse events | 3 months after surgery | Percentage of patients presenting adverse events (ocular and non ocular, severe and not severe), including secondary surgical procedures |
| Patient-reported satisfaction | 3 months after surgery | Level of satisfaction with vision and difficulty performing daily activities, determined by means of the CATQuest 9SF questionnaire, where items are scored in a scale from 1 (yes, a lot of difficulties) to 4 (no, no difficulties) and a cannot decide option. Satisfaction is scored from 1 (very unsatisfied) 4 (very satisfied) and a cannot decide option |
| Contrast sensitivity function under mesopic conditions | 3 months after implantation | Contrast sensitivity measured under mesopic conditions for spatial frequencies of 1.5, 3, 6 and 12 cycles per degree using the Clinical Trial Suite in logCS units |
| Contrast sensitivity function under photopic conditions with glare | 3 months after implantation | Contrast sensitivity measured under photopic conditions inducing glare, for spatial frequencies of 3, 6, 12 and 18 cycles per degree using the Clinical Trial Suite in logCS units |
| Contrast sensitivity function under mesopic conditions with glare | 3 months after implantation | Contrast sensitivity measured under mesopic conditions inducing glare, for spatial frequencies of 1.5, 3, 6 and 12 cycles per degree using the Clinical Trial Suite in logCS units |
| Binocular defocus curve | 3 months after implantation | Visual acuity in logMAR units under binocular conditions, determined varying the stimulus mergence using lenses from -4.00D to +2.00D in 0.50D steps and best refractive correction for distance |
| Aberrometry | 3 months after implantation | Optical quality measured as Zernike coefficients for total Root Mean Square of Higher order aberrations, and Spherical aberrations, expressed in microns |
| Light distortion | 3 months after implantation | Distortion of light as light distortion index, determined by means of the light distortion analyzer |
